FAQ

Does Coupler.io support Basecamp 2 or Basecamp Classic?

No. Only Basecamp 3 accounts are supported. If you're on an older version, you'll need to upgrade your Basecamp account before connecting.

Where do I find my Basecamp API token?

Go to launchpad.37signals.com/integrations while logged into your Basecamp 3 account. Under the API tokens section, generate a personal access token. Copy it right away — you may not be able to view it again after leaving the page.

Can I pull data from multiple Basecamp accounts into one report?

Yes. Add multiple sources to the same data flow — one per Basecamp account — and use the Append transformation to combine them. This works well if your organization manages separate Basecamp accounts by team or client.

Why are my assignee fields showing as arrays or JSON instead of names?

Basecamp returns assignees and participants as lists. The raw output is an array, which some destinations display as a JSON string. Use your destination's split or flatten function to convert these into readable values. See the Data Overview for field details.

Can I get only incomplete (open) todos?

Coupler.io pulls all todos based on your start date. To filter for open tasks, apply a filter in your destination (e.g., a filter on completed = false in Google Sheets or a WHERE clause in BigQuery). This approach is more flexible than restricting the source, since it lets you report on both open and closed tasks from the same data flow.

What's the difference between Schedules and Schedule entries?

Schedules are the calendar tool containers attached to a project. Schedule entries are the individual events, milestones, or deadlines inside those containers. You need to add Schedule entries as its own entity to see the actual events — pulling Schedules alone only gives you the container metadata.

Can I send Basecamp data to an AI tool?

Yes. Coupler.io supports AI destinations including ChatGPT, Claude, Gemini, Perplexity, Cursor, and OpenClaw. This is especially useful for Messages data, where AI tools can summarize discussions, extract decisions, or flag action items automatically.

How far back can I pull historical data?

This depends on your start date setting. You can set it as far back as your Basecamp account history goes. For large accounts with years of data, consider starting with a recent date range, validating the output, then adjusting the start date to pull older records.

For field-level details on each entity, see the Data Overview. For connection errors or missing data, check Common Issues.
